Android两种BroadcastReceiver

Android两种BroadcastReceiver：静态和动态。

第一：静态广播的建立。

（1）在AndroidManifest.xml中声明广播

（2）继承广播接收，对接收到的广播进行处理。

第二：动态广播。

（1）进入Activity时注册动态广播

（2）离开窗口时注销动态广播

实例：

第一：静态广播；

（1）在AndroidManifest.xml中声明静态广播；设置广播接收的动作名

<receiver android:name="广播所在的包名.TestBroadcastReceiver">
<intent-filter>
<action android:name="broadcast_static_action"/>
</intent-filter>
</receiver>

     （2）继承广播接收，对接收到的广播进行处理

public class TestBroadcastReceiver extends BroadcastReceiver{
private final static String TAG = TestBroadcastReceiver.class.getSimpleName();

@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
String staticAction = intent.getAction();
if(staticAction.equals("broadcast_static_action")){
Log.i(TAG,"staticAction");
}
}

}

第二：动态广播

（1）建立动态广播类：

class TestDynamicBroadcastReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
if("broadcast_dynamic_action".equals(intent.getAction())){
Log.i(TAG,"intent.getAction()="+intent.getAction());
}
Log.i(TAG,"dynamic broadcastreceiver");
}
}

（2）建立动态广播对象

BroadcastReceiver receiver = new TestDynamicBroadcastReceiver();

（3）注册动态广播

public void registerBroadcast(){
IntentFilter  intentFilter = new IntentFilter();
intentFilter.addAction("broadcast_dynamic_action");
registerReceiver(receiver, intentFilter);
}

（4）注销动态广播类

public void unRegisterBroadcast(){
unregisterReceiver(receiver);
}
